Embodiments are directed towards managing memory for an application be executing in a managed runtime environment. Managed peer objects may be generated to correspond to native objects executing in a native runtime environment such that memory may be allocated for managed peer objects. Garbage collection handles may be generated and associated with the managed peer objects. If the managed application executes instructions that interact with the managed peer objects and the native runtime environment each garbage collection handle associated with the managed peer objects may be modified based on a type of an interaction. The garbage collection handlers may be garbage collection roots for a garbage collector that may be included in the managed runtime memory manager. If a garbage collection event occurs, memory for the managed peer objects may be deallocated based in part on its correspondent garbage collection handle.

Runtime memory management using multiple memory managers

Embodiments are directed towards generating applications that include multi-sized types running in managed code. During the compilation of an intermediate language version of an application, if a multi-size type is encountered, a runtime engine may perform actions to process the multi-size types. Accordingly, architecture information associated with the target computer may be determined. Data types corresponding to the architecture of the target computer and the multi-sized types may be determined based on the architecture information. Native code calls associated with an intermediate language code calls may be determined such that the parameters of the native code calls match the architecture dependent data types. And, a machine code version of the intermediate language code call may be generated. The generated machine code version of the intermediate language code may be executed with the data types specific to the target computer.
